well, not too bad ... i think. i was recording for about 6 hours today
with an alsa 1.09RC2 driver, and didn't get any kernel oops from that ...

however, i'm not sure if i did exactly what was necessary to update to
RC2 - i just downloaded the driver package and built and installed that
as per one of your earlier suggestions:

and, although everything seems to run fine, i get this in "dmesg":

snd_seq_dummy: Unknown symbol snd_hidden_kcalloc
snd_seq_dummy: Unknown symbol snd_hidden_kfree
snd_seq_dummy: disagrees about version of symbol
snd_seq_create_kernel_client
snd_seq_dummy: Unknown symbol snd_seq_create_kernel_client


i've never been sure about updating alsa ... is it only necessary to
build and update the driver, or would i have to install the libraries
and alsa-kernel package as well? if it's only the driver that need be
updated, then i guess RC2 is not quite working proper here - the only
way i can see that the "dmesg" warning above is having an effect on my
setup is that the midi-thru ports that showed up in recent versions of
alsa is now gone.

i got the latest cvs, too, compiling and installing just the
alsa-driver, and get exactly the same warning in "dmesg".

i miss FC2 :(
